I am not wise in this field, but I experienced this first hand and have enough facts that can end an ongoing debate in the firearm world. Does .22 Caliber LR rimfire ammunition matter?

My immediate answer would be yes, but that would not settle this case. I recently became a full-time adult member (I turned 18) at West Falls Conservation Society in West Falls, New York. My whole life I had been a junior member – it is where I grew up and a big reason why I have a welded relationship with the great outdoors.

One of the benefits of being a member of this organization is the private rifle range. Last July, the summer of 2019, I had used my privilege to open that big red gate with my key to the range! With me, was my guest and very good friend Alex. Alex had his Savage MKII .22 caliber bolt-action rifle with iron sights and I had mine, a .22 caliber Rossi single-shot, break-action, youth rifle with a 3-9x32mm Bushnell Sportsman riflescope.

I had sighted my rifle in once a few years ago, except I received a bit of help from my Grandfather. Knowing the rifle had not been shot in so long, I purchased Federal Champion .22LR 40-Grain ammunition. Packaged in 50 count boxes, I bought four.

We set up our targets 50 yards out. Mine was on the left and Alex was on the right. Before shooting we both went over the range rules posted on the back wall and our own firearm safety precautions. Which were basic and included keeping the barrel pointed downrange, always have the safety switch on (if there is one) and the action open when handing the rifle to one another, both of us would go to check targets with the rifle in hand, and most importantly ALWAYS treat the rifle as if it were loaded and live.

It’s Time to Shoot

Alex begins shooting and I begin the sighting process. I grab three sandbags from the range cabinet and stack them in a pyramid-like shape, the bottom two are parallel with one another and the third sandbag lays across the bottom two in a perpendicular manner. I used this setup as a rifle rest to eliminate any human movement and achieve the greatest accuracy possible. The most proper way to sight in a rifle is to use a gun vise, which I do not have available to use, so the sandbags were my next best thing.

Officially, to start the sight-in process, I rest my rifle on the sandbags, put the crosshairs directly over the center of the target, slowly let out my breath, and gently squeeze the trigger. To my amazement, I hit the target, but not where I was aiming. To tell whether it was my scope or my excitement of taking the shot, the bullet hole was two inches to the right and 3 inches low. Hmmm, I thought. To see if it was me or the ammo or something else, I decided to take 5 more shots identical to the first. Immediately there was a grouping of 6 holes on the light cream-colored target, all within an inch of each other – perfect.

This let me know that my rifle was shooting straight and I needed to adjust my scope. I unscrewed the elevation and windage adjustment caps. I gave 10 clicks counterclockwise on the elevation adjustment (up) and 7 clicks clockwise on the windage adjustment (left). I took my next three shots at the target and to my surprise, they had all hit the bullseye.

To clarify my observations of the target sighting and gun and ammo, I took 10 more shots. – all in the bullseye. I was thrilled! First time ever sighting in a rifle on my own and I did it perfectly? I couldn’t believe my own eyes. From there it was a great day of target practice.

CCI Hollow-Point, 22LR 40-Grain Ammo

It was now March of 2020, I had no more Federal Champion .22LR 40-grain ammunition. Instead of taking the long drive to Cabelas, on the way to West Falls, I stopped in at The Valley Gun Shop in West Falls, NY. I had never been here, but I thought it was time to say hello, introduce myself, and to check it out. The gentlemen who owns the shop only carried CCI hollow-point 40-grain ammunition for .22 caliber rifles. I decided to purchase those and see how they shot. I figured they would probably not shoot the same as the Federal ammunition, but wanted to try them and compare anyway.

As I took my first 3 shots on the target. They all shot to the left 2-inches and 1- inch high, creating a nice small group. I concluded to compensate for the change rather than adjust my scope due to how nicely it was sighted in with the federal ammunition. 100 rounds and 2 trips to the range later, I was out of ammunition once again. I acquired some Winchester .22 LR 40-grain ammo, four boxes.

The Winchester .22LR 40-Grain ammo was simply not consistent for the first 100 rounds fired. I then cleaned my rifle hoping that removing the usual spent powder and metal fragments the other two ammo types would provide a better bore for the bullet to travel through. Again my first 15 shots were inconsistent, as much as 3-inches high, low, left, or right. All over the place.

Now, on the 16th shot after the barrel had been cleaned, to my disbelief, I see nothing more than a hole in the dead center of the target. I thought my luck had changed with this ammunition, but that was not the case. I would have to say every 2 to 3 shots, I would have one round that would shoot straight at 50 yards. What surprised me was that at 100 yards these bullets were landing exactly where I wanted them to with very little pattern change. The only difference I had to adjust for was aiming about 3 inches above the target to hit the bullseye. Hard to analyze.

Best Ammo (for my Rossi)

Testing the ammo types was educational and fun. While these ammo brands might perform differently in other rifle brands, I would have to conclude from live-fire testing that for my break-action, single-shot Rossi, the best (most accurate and repeatable) ammo out of these three brands was the Federal .22LR 40-Grain. Not only does the gun powder smell fresh (hard to describe), the crisp sound of the shot was consistent and the ammo performed consistently. Above that, I never had a misfire in those 200 Federal rounds fired.

Lessons Learned

Before going hunting with any brand of ammo, make sure you test it and know what it does in your firearm.

Hindsight and Future Thoughts

It was especially enjoyable to use the range as a regular member and share it with a friend. In summary, think I’m ready for squirrel season!
